The principal says this is "the worst event that I've ever had to deal with." • Scientists at the American Psychiatric Association's annual meeting are discussing the addition of a condition known as olfactory reference syndrome, a disorder in which people wrongly believe they smell unbearably bad. Suffers become convinced that their bodies are emitting horrible smells, but in reality, they smell absolutely fine. Dr Katharine A. Philips believes the disorder is under-recognized: "I would say it's more common than we know. When I mention it to clinicians, they say, 'Oh, I have a patient like that.'" • Researchers from the University of Aberdeen have found that women who were born prematurely or who have brothers or sisters who were are 50-60% more likely to give birth to a premature baby.
